Updating dataset to database

Well when I run my applications now I don't get any real error, but the data base is NOT being updated Please have a look at my code below and tell me what to do in order to be able to update my data base with a changed Data Set. Page { private Data Set my Data Set; private Data Table my Data Table; private EBBWS. Hi Wencui Qian Thank you for your willingness to help me I tried to put the line: my Sql Command Builder.The code behind in my cs file looks like this: public partial class Profile Info : System. EBBWeb Service my WS; string db First Name, db Last Name; string session User ID = "1"; protected void Page_Load(object sender, Event Args e) protected void save Button_Click(object sender, Event Args e) But it doesn't work I get this Error: "Data Table already belongs to this Data Set." I can understand the error, because after all what I am trying to do is to change data which already exists in the dataset. Get Update Command(); Into my DAL code, but I still get the same error: "Data Table already belongs to this Data Set." Obviously I am doing something wrong when I try to update the Data Set with the updated Data Table, my code looks like this: Hi, If your problem is with saving, why dont you loop through your datatable records and save each single row seperately. Accept Changes(); If you call this method before updating, all the row states will be updated.For more information on saving data from a single data table back to a database, see When updating related tables in a dataset, it is important to update in the proper sequence to reduce the chance of violating referential integrity constraints.The order of command execution will also follow the indices of the .Here I want to let you know that every changes that we have done with dataset, Dataset retains the Row State value for each row and then according to this Row State value.It perform the appropriate operation(Insert or Update or Delete).I am trying to get this to work in a simple example.

Now I want to be able to update the data base with changes made in the user interface of the Website.

For the latest documentation on Visual Studio 2017, see Save data back to the database on docs. If you modify that data, it's a good practice to save those changes back to the database.

You do this in one of three ways: When you data bind dataset tables to controls on a Windows Form or XAML page, the data binding architecture does all the work for you.

As Gordon Linoff pointed out your sql statement is incorrect.

And also setting parameters and the values need to be change depending on the type of the parameters.
